This is an excelent book. I did the progrman when I was 12 but a teacher helped me. The images of the booka and the little ghosts motivated me for days. i lost it decades ago but I still remember.
To create your own game in a time of the gamebooks, arcades and consoles just by reading a book (and a teacher who can count beter than you and see the errors or programing) it was really an acomplishment.
Noe we have more tools but this book shows how to motivate.... children with too much imagination!

My dad bought me a TRS80 Coco2 with a tape deck when I was 7. When I wanted to learn how to program it about a year later mom would take me to the library to get different books. A lot of them were over my head or didn't take time to explain what you were typing. Just a list of code to copy and follow. This book was so different the way it explained what the code did and how the computer understood it. It was my Rosetta stone. I loved this book so much mom bought it from our library. Mainly because I wore the spin out of it and she figured she'd have to pay for it anyhow. I can't stress how important this book was for me. I learned to write basic which I later used to make a science fair project, at the request of my 8th grade science teacher, where me and two buddies wrote a text RPG for school and won the science fair with it. I later moved to PC and after that I went on to sell a game on Xbox Live Indie Games, then one on Windows 10 and Xbox One. The $10 bucks mom spent and this book changed me from playing games to making them. It helped me understand how it worked internally and if I could ever find another copy, as mine wore out, I would happily buy it again. I couldn't recommend this enough for those tinkering with the Color Computer Emulators or even original hardware.
